I agree with Lazlo.
According to section 3.9 of the INF specification (https://edk2-docs.gitbooks.io/edk-ii-inf-specification/3_edk_ii_inf_file_format/39_[sources]_sections.html),
all source files (including module header files) must be listed in the [Sources] section.
Here is the quote:
"All HII Unicode format files must be listed in this section as well as any other "source" type file, such as local module header files, Vfr files, etc. "

So, if file X is used by module Y, but is not listed in Y.inf, it's a violation of the INF spec., which makes it a bug that has to be fixed.
